Dr. Robo is a dreamer. The world to him is much more than binary code, it's his future empire. With the aid of his minions and an army of mini-Dr. Robo clones, he has plans for world domination and robot love. He was once on the path to become an evil doctor, but Robo rebelled against his parental units to follow his dreams.
Each mastery level adds another card to the cardpool for defeating Dr. Robo. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
